Sustainability may not be all it’s cracked up to be. That is the message in a recent paper by a hydrogeologist at Reading University . Michael Price argues that most human advances have been non-sustainable in the long term and that when we talk of ‘sustainable use’ we must define the period over which the use is planned or implemented.
Price identifies three major challenges currently facing Britain and the world. The first is that the climate, and with it the supply of water, is becoming less predictable. Since 1975 Great Britain has suffered four droughts, each of which has been estimated to have a return period of more than 200 years. In 2000-1, parts of England experienced some of the worst instances of flooding on record. Global climate models predict that we can expect more droughts and more periods of heavy rainfall accompanied by increased occurrences of flooding.
The second challenge is that the global demand for fresh water will increase, as population increases and the standard of living improves. It has been argued that in Britain we can counter this increased demand by metering water and making it more expensive. However, consumption of water per head of population in Britain is below that of many other developed countries where domestic water is metered. The stark truth is that demand for water is almost directly related to prosperity - as disposable income increases, water use increases.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
